Surprisingly absent until now, touchability has finally made it into the KDDI au line-up. Casio's offering utilizes a 3.1-inch touchscreen for some funky music apps — making it a music studio in your pocket.

The screen swivels around a central hinge to hide the phone's regular numerical keyboard. Through a Yamaha piano app program, you can also play and record various other instruments on-the-go. Sounds like a fun concept, but it's hard to tell if the phone's specced out enough to handle that kind of program smoothly.

Also included in package: motion sensing, an "urban fitness program," a 5MP camera and 500MB of internal memory. Per usual, only available in Japan for now. [KDDI au]
